The Colorimetry Research CR-250RH is a compact, high-resolution spectroradiometer with a 4nm bandwidth and 1.6nm/pixel optical resolution.
ColourSpace Integration, Large 20+mm Spot Size, 4nm Spectral Bandwidth
Uniquely, the CR-250RH has a large 20+mm spot size, with small divergence angle, making it ideal for contact and non-contact measurement of all displays and projectors, and is designed for all display types, including projection and all luminous display technologies, in contact and non-contact modes. Construction is extremely rugged, made of machined aluminium and stainless steel, with all optical components fixed to ensure no optical misalignment can occur, and weighs only 1 pound (0.45kg). All CR-250RH probes are calibrated using NIST traceable calibration standards at a colour temperature of 2856 Kelvins, using a laboratory grade scanning double monochromator and high accuracy filters of known transmittance and chromaticity. Essentially, no other spectroradiometers are used during manufacturing and Q.A. because none of them are as accurate as a laboratory grade scanning double monochromator.
